6700v3 5G network suddenly not joinable
Where to start… Bought a new modem recently after upgrading internet cm1200. Was getting good speeds when connected via Ethernet to modem but quickly noticed that when running through router it would drop to 200 mbs for all wired devices. So spent the next day going through troubleshooting and found the solution on here. Rolled back firmware and did a factory reset. This fixed the slow Ethernet issue. Today out of the blue my 5G wifi just stopped working and now when I try to connect it continuously fails. I’m the log it shows with Mac rejected when trying to connect from my phone. Tried changing name/password factory reset un plug and plug back in after thirty seconds reset all devices. About everything I can think of. Didn’t change any settings since factory reset so I’m clueless and about ready to waste money on something else. The lights on and the network does show up but sometimes shows up delayed. Thanks for any help given!

Has a full power OFF of the ISP modem and router for 1 minute then back ON been performed?
What happens if you disable WPA security on 5Ghz and leave it open for a few minutes..can you connect then and keep connected or does it still fail? Re-enabled WPA2 and AES after checking this.
Try changing channels on 5Ghz...
- Thanks for your response! So I tried all of your recommendations one at a time this morning. I unplugged power To both modem and router for one minute. Switched security for that network to none and tried to connect (still says unable to join). Changed back to WPA2-PSK [AES] then tried changing to a couple different channels. Still having same problem. The weird thing is that the network seems to not show up very quickly, the 2.4 shows up right away but the 5G takes much longer to show up to attempt to connect to. Let me know if you have any other suggestions to try out, thanks for helping.
Possible that the 5Ghz radio is going bad or has gone bad.
If the router portion is working you could keep the router going, disable all wifi radios and connect up another Wifi AP via ethernet to the router and have good wifi again.
